Charge transfer and photophysical properties of DSSCs based on different π-conjugated bridges: DFT and TD-DFT study.

Dye-sensitized solar cells (DSSCs) are photovoltaic devices that directly convert solar radiation into current, in which the dye sensitizer serves as a critical structure that plays a significant role in determining the performance and conversion efficiency of DSSCs devices. In this paper, a series of D-A-π-A type dyes are designed, in which 2,2'-bithiophene, 1,1'-biphenyl as well as C=C and azo groups are used as π-conjugated bridges to transport electrons, respectively. The ground and excited state properties of several molecules were analyzed by density functional theory (DFT) and time-dependent density functional theory (TD-DFT).

Molecular Design, DFT Study and Optoelectronics Properties of Several DSSCs Sensitizers Based on Different Donor Groups.

Dye-sensitized solar cells (DSSCs) are a type of high-efficiency solar cells that can absorb sunlight using a dye sensitizer positioned on top of a titanium dioxide layer. The sensitizer is the core component in DSSCs, and the photo-to-electric conversion efficiency of DSSCs can be significantly improved by optimizing the dye sensitizer structure and properties. In this paper, a set of D-A-π-A sensitizer (SHY1 ∼ 4) were designed by modifying different donor groups and analyzed their charge transfer and photophysical properties.

The migration characteristics of nanoplastics (NPs) in the natural freezing process are complex and have attracted increasing attention in simulating natural freezing in recent years. However, simulated freezing conditions often fall short of replicating natural freezing processes, and studies on the vertical distribution of NPs remain inadequate. This study established a more realistic simulation of the natural freezing process in surface water by controlling both the air temperature () and the water temperature ().

Spatial variations and vertical migration potentials of petroleum hydrocarbons with varying chain lengths in soils of different depths: Roles of solid and dissolved organic matters and soil texture.

This study explored the occurrence characteristics and spatial variations of different PHs at the depths of 0-10 m in an abandoned industrial site, as well as evaluated the effects of solid organic matter (SOM), dissolved organic matter (DOM), and soil texture on the migration potentials of PHs with varying carbon chains. Furthermore, the leaching potentials of different PHs were integrated into their risk assessment.

Differential uptake and translocation of perfluoroalkyl substances by vegetable roots and leaves: Insight into critical influencing factors.

Crop contamination of perfluoroalkyl substances (PFASs) may threaten human health, with root and leaves representing the primary uptake pathways of PFASs in crops. Therefore, it is imperative to elucidate the uptake characteristics of PFASs by crop roots and leaves as well as the critical influencing factors. In this study, the uptake and translocation of PFASs by roots and leaves of pak choi and radish were systematically explored based on perfluorobutanoic acid (PFBA), perfluorohexanoic acid (PFHxA), perfluorooctanoic acid (PFOA), and perfluorooctane sulfonate (PFOS).

THBru attenuates diabetic cardiomyopathy by inhibiting RAGE-dependent inflammation.

Diabetic cardiomyopathy (DCM) is a complication of diabetes mellitus characterized by heart failure and cardiac remodeling.
